Here is the favorite book of my two children (2 and 3 years), they love and know by heart! The illustrations are cute (with a touch of humor for parents: the school teacher is a slut ...) and history is excellent. She says the first day of a little bear, which is very bad mood. He said no to everything (like yours, it does not remind you of your own child some days?) Then how her return will happen? Is he going to continue to do his "pig-headed"? Is he going to make friends anyway? Ideal to talk with his children these days super annoying "non-on" and to evoke his own back to school.
